SIGNOBS TO THE MILLER COMPANY, OF MERIDEX, CONNECTICUT, A CORPORATION or commcrrcu'r PVATENJ OFFICE ia'ieerira I The presentinvention relates to heaters,

andvis more particularly directed toward a portable heater employing liquid fuel. 7

The: present invention contemplates a portable heater having a body made up 'of sheet metal parts, designed so as to becapable of easy'assembly and yet provide a structure of pleasing appearance, and with sufiicient strength and rigidity. to be of service 1 as a room heater as well as an oil stove.' The invention also contemplates a portable room heater provided with a burner and chimney of the'type ordinarilyused in oil cook stoves, and wherein the fuel supply is carried in two or more tanks. c i

Y The arrangement of the fuel supply system is such that fuel will be taken from one of.

the tanks before it is taken from the other tank, thus making it'possible to have a tank of fuel held in reserve,- andrmaklng' 1t unnecessary to refill two partially emptied tanks. 7 Other and further objects of the invention will be apparent as the description proceeds; The accompanying drawings show, for; purposes of illustrating the present invention, one embodiment in which the-invention may take form, it being understood that the tionof the arrow 2 of Figureyl, and show ing, in dotted lines, the cover in partly raised position; 1

Figure 2a is a fragmentary sectional View of the upper rear corner of the heater as it appears in Figure 2, and showing the sup-' port for the cover plate;

Figure 3 is a vertical sectional View on the line 33 of Figure 1; p I a Figure et'is a horizontal sectionalview on the line H of Figure 1; and

on the broken;

Figure 5 is a fragmentary top plan view showing the grate over the burner.

The base plate of the heater is indicated at 10. It is preferably made of heavy gauge sheet metal pressed downwardly at the edges to form reenforcing walls, 11,12, 13 and 141. The lower edges of these walls may be doubled back, as indicated at '15 in Figure 1.

Four leg formingmembers 16 are secured to the corners of the base plate 1O by means of bolts indicated at 17. These legs are made out of sheet metal and extend downwardly and outwardly to fit inside of a drip pan indicated at 18. This drip pan is made of sheet metal and is provided with upwardly and inwardly sloping walls, as indicated in the drawings, to cooperate with the outwardly flaring legs whereby the pan remains attachedto the legs and may be moved with the heater when it is carried about.

The legs 16 have upwardly extending ,por-

at 24:, and at their upperedges, as indicatedat 25. The lower edges 24 rest on top of the 2 base plate and the side flanges 23 stifien the side panels and provide door openings. The

;upper flanges 25 stiffen the upper edges of these side panels and deflect the heat inwardly. v

Near the corners of the side panels, cover plate supporting brackets 26 are secured, as, for example, by welding them in place. These brackets extend abovethe upper edges of the side panels and support a cover plate 27; this cover plate being secured in place by bolts 28 passing through the brackets 26.

The cover plate 27 has depending'fianges indicated at 29 to stiffen the construction and cover the space above the'edges of the side panels, as will be clear from Figure 2a. This cover plate extendsthe entire length of the heater and is providedwith an opening 30. A grate 31 of suitable construction is secured to the top cover plate about the opening. This grate'may be made out of straps ofsheet V metal welded to the cover plate and may carry a centrally located heat deflecting plate 32. Carrying handles 33 are secured to the depending flanges 29 of the cover plate, and a hinged cover 84 is secured to the cover plate 27 by a hinge indicated at 35.

The end openings of the heater body are adapted to be closed by doors indicated at 40 and 41. These doors are hinged, as inclicated at 4-2 and 43, to plates 44 and45, secured to the upper extensions 19 of the legs 16' by bolts 46. The doors may be held in closed position by the catches 17 and 48. The catch.

may be made out of a knob and bent piece of sheet metal, as indicated, the catch passing: up inside of the flange 29 of the coverplate.

The inside of the heater body is divided into two compartments or-sectionsby a: partition 50, also made of sheet metal, and secured in place by bolts 51 passing through flanges 52. This partition is flanged at the top and bottom, as indicated at 53, to stiffen it. The partition is placed nearer to'one end of the body than the other, as willbeapparent from the drawings, and carries a channel shaped member 54 forming an air-space;

The fuel supply systemis here shown in the form of two independent fueltanks or hottles and 61. These bottlesaremade of glass and are of identical construction. They have the usual threaded cap or cover-member of the tank so as to be below the level of'the delivery outlet of the bottles, and so-that the fuel in the tanks may'seek a common'level.

As shown in the drawings, thesub-tank 64, at the left of FigureB, isdeeperthan the subtank at the right. This will place the bottle 60 at a slightly higher elevation than the bottle 61 and, hence the outlet ofthew bottle 61 will be submerged when the outlet for the other bottle is admitting an air bubble to allow fuel to flow out.

- The fuel outlet isin the form of a pipe 68,

secured to the sub-tank 65 and adapted "to pass down through an opening 69 in the base 10. This fuel pipe extends along underneath the base 10 and is providedwith aburner connection indicated at 70. The other endof the pipe 68 extends out through the flange 12 of the base plate and is provided with aclean out plug 71.

The burner is indicated at 72. This burner is secured to the burner connection 70 by a coupling indicated at 73; Itrests ontop of the base plate 10 and is held in-place' by a circular ring 74;, as indicatedin Figures land lat. If desired, the burner may be more securely held in place by a bent wire member indicated at 75, the upper end of this wire member being looped over the cross strap 76 ordinarily employed in the burner, and the lower end 7 7 being passed through a hole 78 provided in the base 10. The burner 7 2 may include the usual flame spreader, chimney and other devices ordinarily em ployed in oil stoves In assembling the heater, the heater body may be completed as a unit. and. the fuel supply, unit assembled to include the sub-tanks 641 and 65, tube 67 base 66, pipe 68, and burner connection ZOM- This unit is passed in through the door opening at the left and the pipe. passed throughthe: hole. 69 in thebase plate; lzhe. entire unitmay be-movedon. into place and, the clean out plug 7.1 secured: on: the end: of the pipe The burneris; then attached and this completesthe. fixing of the, fuel system.- parts in place;

In orderthat the bottles 60.:and' 61 may be held against. accidental upsetting, clips 79, of; bent spring metal, are provided. They I are secured to. a cross strap, 80, attached to the.flanges 52 of thepartition strip 50.

The side and. end. walls of the heater body' may be providedrwithair openings about the bottom, as indicated at.8l,,and-.about thecside:

and end walls, as indicated at 82. Thecov-er 3.4; may be; provided. with ventilationx openi'ngsgas indicated at 83. The door. 401' is pro-- videdg with the. usual; side opening 84ntoipermit' observation of. the burner;

Whenthe heater. is in'use,.both tanksmaybeifilled-with. fuel,.but,.o.wing*to the fact that one of the tanks is at a higher elevation than theother'tank, .fuel flows fromthis 'tank first.

As sh'own, the tank 6.0 is the higher one. and,

hence, thelowering of thefuel will open the inlet. of this tank. before: it. opens the: inlet of: theother: tank. If the fuel supply is exhausted. from the-tank; or bottle 60, the? fuel willibe drawn from: the tank or bottle6-L The heater is. particularly adapted for room heating when a kerosene burner will supply sufiici'ent heatl'forswarming I the room.

It also. has an' eflicienta burner and v has av suitable-grate wherebyiit: may be used asa single burner oil stove for. cooking purposes,

the" grate 31 being available; to supp'ort" the cooking utensil, or: a small oven: may be:

placed over the opening 301 It-isobviousthat the invention may be embodied in many' forms and: constructions within the scope of the cla1ms, andwe w-1sh it to be understood that the particular form shown is-but one of'the manyforms; Various-modifications and changes being possi ble, we-do not otherwise limit ourselves in any way with respect 'theret'o;
